COMBINATION WINDOW AND vnmrinaron,

Application filed November 3, 1921. Serial No. 512,674. 1

To all whom it may concern:

Be it known that I, HALvnR R. STneIGHr, a citizen of the United States, and a resident of Adel, in the county of Dallas and openings or to direct a current of air from the window openlng through the conductor directly into the interior of the building, and also so arrangedthat the amount of circulation through the conductor or directly into the building may beregulated.

A further object is to provide mechanism which may be applied to the ordinary window frame, andalso to adjoining joist members in the building in such a manner :that a portion of the joist may be adapted to serve the purpose of an air conductor which may be made to communicate with the window opening by merely swinging the window to an opened position.

A still further object is to provide a ventilating device havin a controlling member openlng to the opening 16, I have provided adapted to be move to'a. number of positions in order to controltheamount of air passing through the'ventilator, new and improved means for locking the controlling member in any one of its adjusted positions. I

These and other objects will be to those skilled in the art.

My invention consists in the construction, arrangement and combination of .the various parts of the device, whereby the objects contemplated are attained, as, hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of a segment of a building wall showing the interior side and the manner in which my improved ventilating device is appliedto a window opening.

Figure 2 is a sectional View taken on the line 22 of Figure 1.

Figure 3 is a horizontal sectional view taken on the line 33 of Figurel. v

Figure 4 is a sectional view of my imapparent proved ventilating device as applied to the floor joist and the window frame of a'buildmg. I I

The numeral 10 indicates a wall which may be either masonry or wood construction,the said wall being provided with a window opening 11 in which is mounted a ,wlndow frame 12, which is substantially of the. ordinary construction.

Supported in the wall 10 is a series of joists 13 which are preferably so arranged that one of the joists will rest in the wall at a point directly above each of the vertical members of the frame 12, as clearly shown in Figure-1.

These joists are designed to carry a floor 14 which is also of the ordinary construction. Secured to the under side of two joists, which are immediately above the window opening is a floor portion 15 designed to be carried along substantially to I the center of said joist and spaced from the outer wall so as to provide an opening 16 between the wall and the edge of the floor 15. The space between the floors 14 and 15and between the joists 13 forms an air conductor so arranged that as air is passed through it from its outer. end to the inner end, the air may be made to dischargein the central portion of the building.

For conducting the air from the window a plate 17 adjacent to the inner face of each of the joists l3 and extending through the opening 16, having its outer edge adjacent to the wall 10, and an outwardly projecting portion 19 which is secured to the inner face of an adjacent vertical member of the .frame12. The member 17 extends substantially two-thirds of the distance from the joist 13 to the bottom of the window openmg and has its inner edge inclined upwardly and laterally from the side of the wall, as clearly shown in Figure 2.

Each of these inclined edges is provided =with an angle iron 20 having one of its members riveted to the edge of said plate while its other member extends toward the opposite plate in such a manner, that a flange 1 The upperends of the members 20 are provided with a horizontally arranged board 21 having its upper edge adjacent to the floor 15 to form a portion of the conductor member before described.

By this construction it will be seen that the space between the lower edge of the board 21 and between the members 1'? forms an opening which is either in communication with the window opening or either with the conductor above described.

For closing the window opening, I have provided preferably a window 22 which is held against outward movement by means of stop members 23. The lower edge of the window sash is provided with a flange 2a designed to enter a groove 25 in the lower portion of the frame 12 in such a manner that means is provided against rain being driven into the space between the lower edge of the window sash and also for providing a sort of a pivot on which the window is designed to swing, and furthermore to prevent the lower edge of the sash from inward movement.

To prevent the upper end of the sash from moving inwardly, I have provided a plate 26 which is secured thereto by means of a series of hinges 27. The opposite edge of the plate is provided with a curved portion 28 which is designed to rest against the members 20, as clearly shown in Figure 2, when the said window is in a closed position.

This plate 26 is of such a width that it will rest substantially in a position perpendicular to the members 20 when the window is in a closed position, so that the said window will be securely and firmly locked against inward movement when it is in its closed position.

Pivotally secured to one of the members 20, I have provided a bar which is designed to extend across the space between the two members 20, and has at its free end a hook portion 30 which is designed to pass around the opposite angle member 20, as clearly shown in Figures 1 and 3.

Thus it will be seen that as the member 30 is moved downwardly a slight distance that the members 20 will be drawn slightly toward each other, and the said members held against spreading.

The operation of my ventilator is as follows:

Assuming that the window is in the closed position shown in Figure 2 and it is desired to ventilate the interior of the building, the free end of the plate 26 is moved upward with the curved portion 28 slidingly adjacent to the outer face of the members 20. The upper end of the sash may be then swung inward any desired amount.

In this connection, it should be noted that when the said upper edge of the sash is adjacent to the upper edge of the window frame, the euved portion 28 of the plate 26 should be substantially even with the lower edge of the board 21, the plate 26 being of a width equal to the width of the window sash. The sash and the said plate will then close the opening beneath the board 21. In fact, the conductor and also the window opening will substantially be closed when in this posit-ion. A further inward movement of the top edge of the sash will permit air to pass above the top edge of said sash into the conductor and from thence to the interior of the building.

The air may be controlled by slightly opening or closing the window. After the sash has been placed in the desired position, the member 30 may be moved slightly downwardly causing the members 20 to move toward each other and locking the sash in position by frictional contact therewith.

It sometimes happens, however, that it is desired to ventile the interior of the building near the outside walls. This may be accomplished by permitting the sash to drop in the position shown in dotted lines in Fig ure 2, then sliding the sash longitudinally and upward with the members 20 permitting air to pass through the window opening and beneath the lower edge of the sash 22 into the building. The plate 26 will partially close the opening of the conductor formed between the joists 13, or if an upward movement is continued with the sash, the plate will fall in a horizontal position in said conductor, which will permit the sash to be slid upwardly until its upper edge substantially touches the floor 15, thereby permitting a very large amount of ventilation through the window, which will be equal to the entire window opening.

The sash may be held in any one of its last described positions by the bar 29 and the member 30 as before described.

By this arrangement, it will be seen that I have provided a very cheap and simple construction which may be applied to the ordinary window sash and to the ordinary building construction in such a manner that a large number of adjustments may be made to direct the air to the interior of the building or to the outside portion of the interior as desired.

I claim as my invention:

1. A ventilating device comprising a frame having a window opening, an air conductor in communication with the window opening and also in communication with the interior of the building, a window sash adapted to be placed either in the window opening or moved to an inclined position within the said conductor, said sash being adapted to be moved longitudinally while in the inclined plane to increase or decrease the opening between the conductor and the interior of the room, and means for locking said sash in any of its adjusted positions.

2. In combination, a window frame, each of its side members being provided with an inwardly extending plate, said plates being parallel to each other, a window for said frame, means for supporting the window be tween said plates at an inwardly and upwardly inclined angle when the window frame is in a vertical plane, means for adjustably securing said window in a number of raised or lowered positions while in the said inclined position, said means comprising a transversely arranged bar having one end pivoted to one of said plates and the other end adjustably connected to the other plate in such a manner that as the free end of the bar is swung from a transverse position in either direction, the said plates will be drawn together.

3. In combination, a window frame, each of its side members being provided with an inwardly extending plate, said plates being parallel to each other, one of the end members of said frame being provided with a groove, and the oppposite end with a window stop, the inner edges of said plates being inclined upwardly and inwardly, the said inclined edges being providedwith laterally extending flanges, a window for, said frame designed to have its upper end rest against said stop and its lower edge to rest in said groove, a deflector plate pivoted to the upper and inner edge of said window, said deflector plate being designed to have its inner edge rest against the flanges of said plates and substantially at right angles to said flanges when the window is in its closed posititon for the purpose of locking said window in its closed position.

4. In combination, a window frame having each of its side members provided with an inwardly and upwardly projecting plate, said plates being parallel to each other, the inner edge of each of said plates being inclined inwardly and upwardly and provided with a laterally extending flange, a window sash for said frame, means for preventing said sash from moving outwardly when in said frame, a deflector plate pivoted to the upper and inner edge of said sash designed to rest between said plates, the said sash being designed to be swung inwardly to an inclined position between said plates and to rest normally on said flanges, means for adjusting said sash in a number of raised or lowered positions while in the said inclined position between said plates.
